pseudo: Add statx support to fix fedora30 issues
Modern distros (e.g. fedora30) are starting to use the new statx() syscall through the newly exposed glibc wrapper function in software like coreutils (e.g. the ls command). Add support to intercept this to pseudo. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> [Fixup for warrior context] Signed-off-by: Armin Kuster <akuster808@gmail.com>
